I think a blackout roller blind and some nice drapes would be good there are literally 1000s of decals for walls and the nice thing is they removeable as the child grows. You will need more storage for sure . A chair is always nice for feeding and reading a book later .I like a chair with no moving parts since toddlers get into lots of trouble. Get a nice foot stool with the chair.A fun light fixture and a lamp so that you can have just soft lighting in the middle of the night.As the baby gets older a book shelf a low one is a good idea attached to the wall.Toy storage . A mobile above the change table .

What color drapes would you recommend?
